Many of us have experience that emacs cannot run under x2go. https://bugzilla.redhat.com/show_bug.cgi?id=1349412
There is no actual fix, but we can't live without emacs, so I am putting up a version on copr which has a workaround (configure options).
It is named: e.g., emacs-filesystem-25.1-2.x2go.fc24.noarch.rpm
I think this complies with naming conventions.
